Question 1075879: Jane can complete a sales route by herself in 45 minutes. Working with an assistant she can complete a sales route in 40 minutes. How long would it take her assistant to do it alone? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let n be the amount of time it takes for the assistant working alone. Then:
1/45+1/n=1/40
8n+360=9n
n=360
It would take the assistant 360 minutes, or 6 hours, to do the route alone. ☺☺☺☺
